libomron is a mainly C-based implementation of the data retreival protocol for the USB enabled line of omron home medical equipment.
Blood Pressure Monitors * HEM-790-IT * BP-791-IT * M10-IT
Pedometers * HJ-720-IT
While basic communication functions in the library should work for any Omron product, there may be differences in packet layout and measure units between US/European/Japanese/etc products… We will try to cover these as requested, but the library itself is produced in the US, so that’s what I have easiest access to.
A Tale of Two Libraries
libomron comes in two flavors: Win32 and libusb-1.0. The Win32 version uses direct Win32 DDK calls to access the windows HID system, and reads raw reports from there (which means we aren’t required to install any specific drivers.). libusb-1.0 works for all platforms currently supporting the library.
Library Requirements (For Compilation)
CMake (Required on all platforms) - http://www.cmake.org
SWIG (For non-C libraries) - http://www.swig.org
Python (with dev libraries, for python lib) - http://www.python.org
WDK (Windows Only) - http://www.microsoft.com/whdc/devtools/WDK/default.mspx
libusb-1.0 (All non-windows platforms) - http://www.libusb.org
To build on Ubuntu, you can pull the following packages to build the project from source.
For OS X, there are build files available for homebrew and macports.
To build libomron, make a subdirectory in the source dir (called whatever you want), then go into that directory and run "cmake ..". This will generate the project files for your platform (makefiles for OS X and linux, visual studio for windows). For more information on project generators, look at the cmake documentation.
Notes on Compilation and Usage
Mac OS X
You will need to install the "Omron OS X Extension" in order to use omron software on OS X. The file and installation instructions are available on the libomron sourceforge site, or in the mac binary package if one is available. The kext should work on 10.5 or later.
The VID/PID pair of the omron will need to be blacklisted on linux in order to use libomron there without requiring root access. This can be done either in the kernel or through udev.

Brett Viren’s README
(I’m including Brett’s README here because I’m too lazy to integrate it and just want to get 0.9.0 out. :) )
This is a fork of http://github.com/qdot/libomron I use to play around with my 790-IT. Much thanks to qDot for the original heavy lifting! The intention here is to scratch my own itch and feed any useful improvements back to qDot.
This fork adds:
Python bindings via SWIG
Python utilities including plotting, device autodetection
Random bug fixes/improvements on the C side
A simple Python/TK GUI app.
Steps for installation, testing and running
Things are not as polished as they could be, but here is how to go from nothing to something.
It assumes these locations:
git clone to ~/git/libomron
build area in ~/opt/omron-build
install area in ~/opt/omron
0) Clone github repo by going to http://github.com/brettviren/libomron and selecting a method
cd ~/git git clone ...
1) Go to resulting libomron/ directory and install needed qDot submodule (git://github.com/qdot/compily_buildd.git)
cd ~/git/libomron git submodule update --init
2) Create and enter installation directory
mkdir -p ~/opt/omron-build cd ~/opt/omron-build/
3) Run "cmake ~/git/libomron"
4) Run "make" and optionally "make DESTDIR=~/opt/omron install"
5) Plug in USB and find out device
lsusb | grep Omron Bus 005 Device 006: ID 0590:0028 Omron Corp. HJ-720IT Pedometer
(note, my 790-IT blood pressure monitor is identified incorectly, but that is okay)
6) From the numbers above, set this env. var.:
7) Check that it is readable and writable by you:
ls -l $OMRON_DEV groups
8) Finally, run the example to readout stored values
9) Try out the python bindings do:
export PYTHONPATH=~/opt/omron/usr/local/python python ~/opt/omron/usr/local/python/omron/omron_790IT_test.py # (this will make a omron.sqlite3 in current directory python ~/opt/omron/usr/local/python/omron/store.py # (this will dump omron.sqlite3) python ~/opt/omron/usr/local/python/omron/plot.py # (this wlil plot all readouts)
10) Try the GUI app
# Set PYTHONPATH as above, and print help screen python ~/opt/omron/usr/local/python/omron/gui -h # Run it, point it to a data file, can be same one produced above python ~/opt/omron/usr/local/python/omron/gui -f omron.sqlite3
